6 p-Wave Superconductivity and d-Vector Representation

Fig. 6.5 Phase diagram in the temperature–magnetic field space of the superconducting phases
of UPt 3 : the same phases as in Fig. 6.4 are represented, but different gap structures are proposed,
according to the E 1u symmetry (the Fermi surface is reduced to a point in this representation).
The magnetic field H is parallel to the lattice vector b. Reproduced from [10] with permission

6.8.2.4 p-Wave Superconductivity in Sr 2 RuO 4
This system has also early been proposed as a candidate for p-wave superconductivity. In fact, due to the accessible range for the studies (T SC is slightly larger than
1K), and the absence of radioactive elements, as well as the popularity of oxides, it
is certainly the most studied ‘ p-wave’ superconductor ever (for a review, see [12]).
The most ‘fashionable’ order parameter is very similar to the superfluid
3 He A-phase
d(k) ∝ (k x ± i k y )e z .
